Just did a sync and it worked fine....device > schedule world

Then setup evolution to sync and I wound up with doubles of many of my contacts and some calendar events on schedule world and in evolution. I'm using an 8330 with 4.5.

Any thoughts?

Following OPs advice I still have my BB set to one way sync (device > server) and thank God I do. Lol. I need to solve this duplicate issue prior to making my berry sync two way. Thanks in advance for any help as I'm still learning my way around linux (Intrepid Ibex).
